This single-subject pilot study compared the surface agreement of seven 3D facial scanning configurations available on the Ukrainian market against a cone-beam computed tomography (CBCT)-derived reference surface, reporting trueness-related surface-deviation metrics and acquisition time. Because only one participant was examined and no repeated acquisitions were obtained, the work is exploratory and does not establish device precision (repeatability) or population-level accuracy. A prospective comparative pilot acquisition was performed on one healthy adult volunteer at rest on a single day. Three radiopaque fiducial markers were placed over low-mobility sites (glabella, both temporal regions). A CBCT volume (Planmeca ProMax 3D Mid) was segmented in 3D Slicer (v5.10.0) to yield the reference soft-tissue surface. Seven configurations were assessed: Shining 3D MetiSmile, Creality CR-Scan Raptor Pro, Revopoint Miraco Pro, RAYFace Facial Scanner, Planmeca ProMax 3D ProFace, and Qlone Dental App (iPad and iPhone). In CloudCompare (v2.14.alpha), fiducial-based Point-Pairs registration was followed by Iterative Closest Point (ICP) alignment, and cloud-to-mesh (C2M) surface-deviation distances were computed. Only descriptive statistics were used. Across the evaluated low-mobility region, the structured-light devices showed sub-millimetre surface deviation, with Shining 3D MetiSmile and Creality CR-Scan Raptor Pro showing the smallest dispersion (RMSE 0.288 and 0.328 mm). RAYFace recorded the highest proportion of points within ≤ 2 mm (98.74%) and the shortest acquisition time (5 s). Revopoint Miraco Pro and Planmeca ProMax 3D ProFace showed larger but still sub-millimetre deviations. Qlone deviated markedly (iPad and iPhone), with its upper error range approaching the fixed computation limit, so its tail is under-represented. In this single volunteer and over rigid, low-mobility regions only, structured-light scanners showed closer agreement with the CBCT-derived surface than the smartphone photogrammetry application. Differences among the leading structured-light devices were within the expected uncertainty of the reference surface and should not be over-interpreted as a device ranking.

This protocol specifically integrated piezoelectric subgingival finish-line refinement, subgingival mechanical polishing, and four-step ultra-polished zirconia restorations to optimize gingival thickness (GT), marginal positional stability, and peri-restorative tissue health. Four patients requiring fixed prostheses (totaling 35 teeth) were treated using this integrated modified BOPT framework. Following bulk tooth reduction, finish lines were refined using specialized piezoelectric ultrasonic tips and smoothed subgingivally with silicone points. The subgingival emergence profiles of definitive zirconia crowns were managed through a strict four-step ultra-polishing protocol. Periodontal variables-including GT changes across different baseline phenotypes, gingival margin stability, plaque index, bleeding on probing, and gingival stippling-were recorded at baseline, 1 week, 3, 6, and 12 months. At 12 months, stable gingival margins were maintained with no observable tissue recession across all monitored sites. A notable descriptive increase in GT occurred, particularly within the baseline thin phenotype group, which shifted from 0.59 ± 0.09 mm to 1.14 ± 0.23 mm. Furthermore, favorable soft-tissue responses were observed, characterized by minimal bleeding scores and a widespread clinical reappearance of gingival stippling at the 1-year follow-up interval. Within the study's limitations, this modified BOPT protocol demonstrated promising trends regarding soft-tissue thickening and short-term marginal stability. Integrating piezoelectric refinement with rigorous clinical and laboratory zirconia polishing protocols exhibits excellent biological integration and soft-tissue maturation.

To evaluate the efficacy of a Quercus persica extract lozenge in reducing gag reflex severity in adult dental patients.

A cross-sectional investigation was carried out on 75 construction workers from active construction sites in Mangalore, Karnataka, India, aged 20-60 years. Participants were categorized into three groups: individuals with no tobacco habit, those consuming smoked tobacco, and those using smokeless tobacco. The periodontal condition of all subjects was evaluated with the WHO Oral Health Assessment Form (2013). Salivary thiocyanate concentration was estimated with an ultraviolet spectrophotometer set at a wavelength of 447 nm, whereas salivary pH was measured using a digital pH meter. Data analysis was performed using the Statistical Package for Social Sciences (SPSS, version 19.0). To compare variations among the groups, one-way analysis of variance (ANOVA) was applied, followed by Tukey's post hoc test for pairwise comparisons. Gingival bleeding scores were elevated in smokeless tobacco users (100%) compared to smoked tobacco users (88%) and non-users (48%). Periodontal pockets > 6 mm were found in 84% of smoked tobacco users and 76% of smokeless tobacco users, while non-users had none. Mean salivary thiocyanate levels were significantly higher in smoked tobacco users (11.28 ± 1.23) than in smokeless users (7.67 ± 1.08) and non-users (4.26 ± 1.15) (p < 0.001). Salivary pH was lowest in smokeless tobacco users (6.18 ± 0.49), indicating a more acidic environment compared to smoked tobacco users (6.35 ± 0.54) and non-users (7.76 ± 0.45). Both smoked and smokeless tobacco use were associated with poorer periodontal parameters and altered salivary biomarkers among construction workers. Smoked tobacco users demonstrated higher salivary thiocyanate levels, while smokeless tobacco users exhibited lower salivary pH. These findings suggest that salivary biomarkers may reflect tobacco exposure and warrant further investigation regarding their relationship with periodontal disease severity.</p>","PeriodicalId":47246,"journal":{"name":"Saudi Dental Journal","volume":"38 8","pages":""},"PeriodicalIF":2.4,"publicationDate":"2026-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13385283/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148521193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
